Synopsis

Keywords: Contrast mechanisms: Electromagnetic tissue properties

This course gives an introduction to quantitative susceptibility mapping (QSM). Magnetic susceptibility is a measure of how much a material gets magnetized in an external magnetic field. QSM is ideally computed from multi-echo gradient echo data. Phase data need to be processed to remove phase wraps and to compute the local field from which the susceptibility distribution is calculated.
The learning aims are:

• Learn what the contrast mechanisms for susceptibility imaging of biological tissue are,
• What data need to be acquired for QSM,
• Discuss important acquisition parameters,
• Understand basic steps for the calculation of QSM,
• Applications & Resources.
